SET – Micro Spy Bug Operating Outside FM Broadcast Band + High-Sensitivity FM Receiver (Up to 700m) | Spy-IL8
Spy-IL8 SET — Micro FM Spy Bug + Enhanced FM Receiver (Tuned Pair, 77.0 MHz)
• Factory tuned pair: transmitter + receiver matched to each other out of the box
• Clean listening: operates at 77.0 MHz — outside the crowded FM broadcast band (88–108 MHz)
• Long reach: up to ~700 m line-of-sight in open area* (real-world depends on obstacles)
• Easy frequency tuning: transmitter can be tuned from 76 to 110 MHz with one button (see video)
Spy-IL8 is a ready-to-use set for real-time FM audio listening: a micro transmitter (spy bug) and a compact receiver selected to work together. The main advantage is simple — the default operating frequency is 77.0 MHz, which is outside the standard FM broadcasting area. That means much less interference from local radio stations and a cleaner signal in many environments.
The included receiver features an enhanced FM range starting around 63–64 MHz, so it can receive signals in the non-broadcast FM area as well. This makes the set a practical solution for controlled listening, technical testing, and learning how FM transmission works in real conditions.
Need a different frequency? The transmitter can be easily tuned anywhere between 76–110 MHz with a single button. The setup and tuning process is shown in the video at the end of this listing.
